Arterial Brown-Séquard's syndrome after a penetrating injury of the spinal cord at the cervicomedullary junction.

A case of a 12-year-old boy, in whom a partial Brown-Séquard's syndrome developed after a gunshot injury to the back of the neck, is reported. The bullet, which was removed at operation, penetrated the left side of the spinal cord at the cervicomedullary junction. The patient recovered useful function in his left leg within a month after the injury, and was able to walk with the aid of a crutch on discharge from hospital. The case is unusual, because of the survival and subsequent good recovery of the patient after a high, penetrating injury of the spinal cord.
